[Heb-NACO] Talele vs. telale orot

[Robert Talbott]

Good HEB-NACO people:

I have a book here I'm trying to catalog, but there's an issue with the 
title, to wit

[tet lamed lame yud] midrash / Shelomoh Kohen-Doras. Per Even-Shoshan, 
[tet lamed lame yud] is romanized as "talele."  Fine fine.  But when I 
looked in OCLC I found a counter romanization in DLC DLC records, 
"telale." Regarding the latter, the "telale" romanization is followed 
most often by the word "orot."

I looked in my trusty concordance, and struck out.  I consulted with our 
local Judaica authority here in the library and he suggested that it 
might be from the sidur. I've looked and looked, and I can't find it.  
That doesn't mean it's not there, only that I can't find it.

My questions:

1) What's the source of "telale orot?" The sidur?  Something more obscure?

2) More importantly: why "telale" and not "talele?"

Thanks in advance, and happy Friday.

Bob
